IMPROVEMENT IN MACHINES FOR DESTROYING COTTON-WORMS.

Specification forming part of Letters Patent N 0. 154,651, datedSeptember 1, 1874; application filed June 1, 1874.

To all whom it may concern:

Be it known that I, NICHOLAS A. DAVIS, of Rusk, Cherokee county, Texas,have invented a new and useful Machine for the Distribution of Poisonfor the Destruction of the Cotton- Worm, of which the following is aclear, full, and exact description, reference being had to theaccompanying drawings, making a part of this specification,in whicFigure 1 represents my invention attached to-a cart. Fig. 2 is a crosssection through the line y y.

My invention relates to the distribution of poison intended to destroythe cotton-worm in the field; and it consists in the combination ofdevices hereinafter explained.

In order that those skilled in the art may make and use my invention, Iwill proceed to describe the exact manner in which I have carried itout.

In the drawings, A represents an ordinary farmcart, across the rear endof which is secured the horizontal shaft B, having its bearin gs in thearms 0 c, projecting behind the cart. On the shaft B I place two or morelooselyrevolving perforated cylinders, E, bein g revolved upon theshaft, which carries a pulley, a, over which a band or cord works,passing to the hub of the cart-wheel, from which it receives motion, andthus causes the shaft B to revolve when the cart is in motion, and theshaft, carrying the perforated cylinders, previously filled with thepowdered poison, causes the poison to be sifted outand distributed overthe cotton-plants. Attached to the inner end of each of the outsidecylinders is a spiral spring, b, coiled around the shaft A, and soarranged as to secure an easy, gentle, lateral motion to thecylinders incase of a sudden jar given the machine, and thus prevent too great adischarge of the poison at any one point.

It is evident that a similar spring may be used at the opposite end ofthe cylinders, so as to check the jar in both directions.

From the above description of my invention, it is evident that it couldbe affixed to any kind of frame moving on wheels, and by a hand-crankand ordinary cog-gearing be successfully worked; I therefore do notconfine myself to the mode herein described for operating my device, asthe same may be varied without departing from the spirit of myinvention.

.I do not claim, broadly, the use of the revolving cylinders arranged ona shaft, as this is old; but

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The shaft A. cylinder E, and. pulley a, in combination with the springsb, all constructed to operate substantially as and for the purpose setforth.

NICHOLAS A. DAVIS.
